Abstract

 Salah satu upaya strategi untuk mengurangi ketergantungan harga cokelat di pasar internasional adalah dengan perluasan pasar dan diversifikasi produk hilirnya. Kapasitas produksi dirancang berdasarkan jumlah produk cokelat optimum yang dihasilkan per hari dengan formulasi standar. Analisis proses dilakukan terhadap alur proses yang sinambung untuk menghasilkan pasta cokelat, bubuk kakao dan produk samping berupa kulit biji tanpa adanya penumpukan bahan di salah satu tahapan proses. Hasil penelitian menunjukkan bahwa untuk mencegah terjadinya penumpukan bahan (bottle neck) dalam satu alur proses, maka diperlukan pengempa lemak kakao, kabinet tempering bungkil, mesin refining, mesin choncing dan kabinet tempering pasta masing-masing sebanyak 2, 17, 3, 7 dan 5 unit. Dengan asumsi umur ekonomis selama 10 tahun, harga biji kakao kering terfermentasi Rp 25.000,-/kg, harga bubuk kakao murni Rp 75.000,-/kg kemasan, dan formula cokelat Rp 90.000,-/kg, maka diperoleh nilai ROI, BC Ratio, dan NPV (nett present value) masing-masing sebesar  7,4 tahun; 1,45; dan Rp 6.495.903.815,-. Terindikasikan bahwa mutu bubuk kakao dan formula cokelat yang dihasilkan baik dan dapat diterima oleh konsumen.         Kata kunci : Kakao, Cokelat, Proses produksi, Skala UKM

Abstract

Dying is one of important steps in coffee processing to produce good quality. Greenhouse is one of artificial drying alternatives that potential for coffee drying method cause of cleans environmental friendly, renewable energy sources and chippers. Indonesian Coffee and Cocoa Research Institute has developed and testing a big scale greenhouse type dryer for fresh coffee cherries and wet parchment coffee drying process. Greenhouse has 24 m length, 18 m width, also 3 m high of the front side and 2 m high of the rear side. The maximum capacity of greenhouse is 40 tons fresh coffee cherries. Fiber Reinforced Plastic (FRP) used as greenhouse roof that combined with I and C profile of steel. Fresh coffee cherries and wet parchment coffee from Robusta variety use as main materials in this research. The treatment of this research was 30 kg/m2, 60 kg/m2 and 90 kg/m2 for coffee density. String process has done by manual, two times a day in the morning and in the afternoon. As control, fresh coffee cherries and wet parchment coffee has dried by fully sun drying method. The result showed that a big scale greenhouse has heat drying efficiency between 29.9-58.2% depend on type and density of coffee treatments. On the full sunny day, greenhouse has produced maximum drying air temperature up to 52oC. In radiation cumulative level 4-5 kW-jam/m2 per day, 12.9-38.8 tons fresh coffee cherries or wet parchment coffee with 58-64% moisture content can be dried to 12% moisture content for 6 up to 14 days drying process. Slowly drying mechanism can be avoided negative effect to degradation of quality precursor compound. Capacity of the dryer can be raise and fungi can be reduce with application of controllable mechanical stirring in the greenhouse. Keywords: greenhouse, coffee, drying, quality
